I saw this on Craigslist. I didn’t know the existed but what a cool concept.

Looks like a fine piece of equipment.  It would be wasted on me, no room, no 3 phase, no real need for a commercial saw.  I use my ShopSmith on the rare occasion that I need a table saw.

I have never seen a table saw with a rotary arbor system that allows for two arbors, two blades and separate motors for each arbor.

Boy that link brought back some memories!    The shop I taught in had what appeared to be a brother of that saw.  Same fence.  Same colors.  Same big wheels.  Right or left fence positions. I loved that fence.  There was no blade guard or riving knife or effective dust collection, but it had power to either cut through 3" thick oak planks or throw them back at you.  The scars that table saw left on the ceiling, floor, and door behind it were erased when that shop space was remodeled into a lecture hall.  The saw still survives ((I think) in the new fab lab where no one uses it over the Saw Stops saws they added or a big Powermatic with sliding table. There was talk of sending it to state surplus, but no action on that yet when I retired last year.

Very interesting. No doubt a workhorse. Guessing it tips the scales at a hefty amount. Old Oliver equipment like that was intended to last forever. Curious to know what operations required such a saw.

The difficulty in changing out the blade for rip or crosscuts is what I'm sure inspired the engineer(s) of that saw to have two arbors. The Oliver we had only got a blade change when the current blade was clearly dull or had chipped teeth from sawing through hidden metal artifacts in hardwoods). Crosscuts were left to a large RAS with extended side tables.
